If you're interested in biking to work, but not interested in arriving covered in sweat, posits Good, the electric bike might be for you. Electric bikes use batteries to ease the pedaling and give you that extra kick, much like biking downhill everywhere. They're just the thing for a zero-emissions commute and escape from behind the wheel. However, the batteries and other features require an extra level of maintenance and know-how.

The bikes vary from strap-on batteries on the Ezip Trailz to the Kilowatt sustainable bamboo bike. Read the full rundown at Good.
